Tile Gradient Ramp

[ivanjay]

I am trying to create a mosaic tile using Gradient Ramp.

 

I have a gradient ramp with my (3) tile colors set. It is mapping to a tile map in which I am using color variance to generate the black/white colors I need for the gradient ramp.

 

The randomness is great and it looks good....

 

Now, I am trying to get white grout so these actually look like tile....

 

My thought process was to set a flag at 99 (pure white) in the gradient ramp and set the grout in my tile map to white. All the grout is now white and looks good but I am getting white tiles randomly inserted into my mosiac. This makes sense but I need to eliminate this. How can I constrain the color variance to give me only values below pure white? Or.... Am I asking the impossible and need to go about this a different way?

"stack" 'em. Make this complete map the map in the tile slot of another tile map that just has white for grout.

Thanks Peter. I actually figured it out not long after I submitted the thread. I made an error in the stacking which is why it wasn't working.
